This page provides an overview of the available methods on the Chainstack Optimism nodes. Go ahead an try the interactive examples as well.

The table has three columns:

  • Method β€” method name.
  • Availability β€” out of the box on a regional or global node, or on request on a dedicated node since it requires customization.

πŸ“˜

The list may not be comprehensive but serves as guidance. In general, if the method is available in op-gethor in op-erigonand it's an eth_ method, then it's available on your Chainstack node.

If there's a method missing, you are unsure, or just have any questions, talk to us. We love talking to developers πŸ’™πŸ› οΈ.
